DKIST Data Access via the VSO

This directory contains DKIST/DL-NIRSP level 1 data from PID_3_90 observed on 14 April 2025. It was processed by S. Jaeggli on the NSO Maui compute nodes using the preliminary DL-NIRSP pipeline v0.21.0 (2025-02-06). You can see details of this pipeline at https://docs.dkist.nso.edu/projects/dl-nirsp/en/v0.21.0/.

Within this directory there are 6 datasets corresponding to 3 observing programs. Each observing program includes data from DL-NIRSP Arm 1, with the Ca II 854 nm channel, and Arm 3, with the Fe I 1565 nm channel.

This is a preliminary level 1 data product and there are known issues with its calibration. The wavelength has been linearized, but the wavelength offset and dispersion are not accurate. There are still artifacts related to the integral field spectra flat field. Please contact S. Jaeggli (sjaeggli at nso dot edu) with any questions or concerns.

Examples of how to interact with the DL-NIRSP level 1 data products can be found on GitHub at https://github.com/sajaeggli/DL-NIRSP-Data-Analysis.

This release is preliminary and provided to accompany other publicly released datasets collected on 14 April 2025. Upon release of the first version of the DL-NIRSP processing pipeline at the DKIST Data Center, this dataset should be removed and replaced with the most recent Data Center product.
